Verbal and Visual Feedback Immediately Affect the Electromyographic Activity of Female Pelvic Floor Muscles.

Objective: The purpose of this study was to assess the immediate effect of verbal and visual feedback on pelvic floor muscles (PFM) in nulliparous women without pelvic floor dysfunction.

Methods: In this observational, single-assessor, cross-sectional study, 45 female university students were evaluated using bidigital vaginal palpation and vaginal surface electromyography (EMG). EMG assessments were performed at 2 time points (T1 and T2).

Short-term thyroid hormone excess affects the heart but does not affect adrenal activity in rats.

Background: Hyperthyroidism (Hy) exerts a broad range of influences on a variety of physiological parameters. Its disruptive effect on cardiovascular system is one of its most remarkable impacts. Moreover, Hy has been clinically associated with stress - induced hyperactivation of the hypothalamic-pituitary-adrenal axis.

Ethyl 2-cyanoacrylate tissue adhesive in partial lobectomy in rats.

Objective: To determine the efficacy of ethyl 2-cyanoacrylate adhesive in repairing the lung parenchyma after partial lobectomy in rats, in terms of hemostasis/aerostasis, scarring, and surgical time.

Methods: The study involved 30 Wistar rats, randomly divided into five groups (one control group and four study groups). In the study groups, the lung parenchyma was repaired with either cyanoacrylate adhesive or surgical suture following resection of a small or large fragment (25% or 50%, respectively) of the left caudal lung lobe.

Neonatal gene transfer of Serca2a delays onset of hypertrophic remodeling and improves function in familial hypertrophic cardiomyopathy.

Familial hypertrophic cardiomyopathy (FHC) is an autosomal dominant genetic disorder linked to numerous mutations in the sarcomeric proteins. The clinical presentation of FHC is highly variable, but it is a major cause of sudden cardiac death in young adults with no specific treatments. We tested the hypothesis that early intervention in Ca(2+) regulation may prevent pathological hypertrophy and improve cardiac function in a FHC displaying increased myofilament sensitivity to Ca(2+) and diastolic dysfunction.
